Cuisine & Edibility
Tarpon
Bony flesh with a strong, somewhat coarse texture; rarely eaten in modern sport fishing. Primarily catch-and-release; not commonly consumed due to bones and Vulnerable status.
Wels Catfish
Fatty, soft flesh with a mild, slightly sweet flavor; quality improves from cold, clean water fish. Popular in Central European cuisines — commonly smoked, fried, or braised with vegetables.
